Configuring FTP, SMTP, and Telnet Probes

An FTP, SMTP, or Telnet probe establishes a connection to the real server and verifies that a greeting
from the application was received. The probe (ftp, smtp, or telnet) command enters the corresponding
probe configuration mode. All the probe common options are supported. Multiple status ranges are
supported, one command at a time.
To configure a status code to expect from the FTP, SMTP, or Telnet probe, perform this task:
Command
Step 1
Router(config-module-csm)# probe probe-name
[ftp | smtp | telnet]
Step 2
Router(config-slb-probe-icmp)# interval
Step 3
Router(config-slb-probe-icmp)# receive
Step 4
Router(config-slb-probe-icmp)# retries

Specifying the DNS Resolve Request

A DNS probe sends a domain name resolve request to the real server and verifies the returned IP address.
The probe dns command places the user in DNS probe configuration submode. All the probe common
options are supported except open, which is ignored.
